#5837 closed defect (invalid)

crash in CC708Window::Scroll

Reported by: slamb@… Owned by: Isaac Richards
Priority: critical Milestone: 0.22
Component: MythTV - Video Playback Version: head
Severity: medium Keywords:
Cc: Ticket locked: no

Description

I have a .nuv file (a HDTV recording of The Office, captured via a HDHomeRun) which can consistently crash the MythTV frontend. Several points in the video will crash it during normal play, but not during fast-forward.

I don't see any previous reports with this stack trace. Here it is, along with version info. I have the video file as well; I'm not very .nuv-savvy but with a pointer I'd be willing to try cutting it down to a fair use size for anyone interested in reproducing the bug.

Can you please post a full backtrace using the instructions at: http://www.mythtv.org/docs/mythtv-HOWTO-22.html#ss22.2

Resolution: invalid
Status: infoneeded_newclosed

Requested information not provided in 30 days. Please re-open the ticket with the full backtrace, in particular we need line numbers to usefully debug the problem. Alternatively if you can make a sample of video available we will accept this instead, you could try asking on the mailing list about cutting down a NUV.

comment:3 Changed 11 years ago by slamb@…

[Can someone please reopen this? I don't have an account, don't see a way to create one, and without one I get "No permission to change ticket fields."]

I finally hunted down some older Ubuntu packages with associated -dbgsyms (which was easier for me than nuking the distro-installed version and reinstalling from source) and reproduced this to get the line numbers you requested.

While I was at it, I took a look at the code - looks like the direct cause of the crash is that it's incorrectly assuming text is non-null here.

I need a short sample of a video that produces this segfault. I can't see any way to get into a state where this would happen.

For this to happen true_column_count * true_row_count would have to exceed the size of the text array, but the only way for that to happen is if that value exceeds the maximum value of unsigned int and overflows. On all systems we support this is at least 32 bits or 4 gigabytes. This well exceeds the maximums for the number of rows and columns of text in 708 captions.
